Hi,
This is (yet another) update of CMA patches. I've rebased them onto recent v3.4-rc1 kernel tree and integrated some minor bugfixes. The first issue has been pointed by Sandeep Patil - alloc_contig_range reclaimed two times too many pages, second issue (possible mismatch between pageblock size and MAX_ORDER pages) has been recently spotted by Michal Nazarewicz.
These patches are also available on my git repository: git://git.linaro.org/people/mszyprowski/linux-dma-mapping.git 3.4-rc1-cma-v24
Best regards Marek Szyprowski Samsung Poland R&D Center
